INVENTOR BADGER PERRIN ATTORNEY THREE-PIECE TACK BUTTON BACKGROUND OF THE INVENTION An early example of a four-piece tack button is shown in the patent to Peterson et al. US. Pat. No. 2,170,092 issued Aug. 22, 1939, which discloses a cap, a button shell or body element, an anvil and a vise. The cap and button shell hold the separate anvil and a separate vise enclosed and in engagement.

An example of a three-piece tack button is shown in the patent to King U. S. Pat. No. 1,854,845 issued Apr. 19, 1932, disclosing a combination anvil and vise which is held against a cap by a button shell or body element. The combination anvil and vise has a series of spread fingers at its open end which must be controlled from spreading by the button shell. The combination anvil and vise is of single wall construction.

Another example of a four-piece tack button is the patent to Purinton US. Pat. No. 2,179,522 issued Nov. 14, 1939.

The patent to Peterson US. Pat. No. 2,207,022 issued July 9, 1940, discloses a vise and a separate anvil held within a plastic body.

Finally, the patent to Deschene US. Pat. No. 3,137,050 issued June 16, 1964, shows a two-piece construction comprising a cap, and anvil combination holding a separate vise. Theoretically, because it lacks an anvil spaced from the cap, this construction may show marks on the cap when the cap is engaged with the button.

SUMMARY OF THE INVENTION An object of the present invention is to provide a one-piece combination vise and anvil for a tack button.

A further object'of the present invention is to provide a vise and anvil combination for a tack button wherein the vise has a continuous uninterrupted wall.

A still further object of the present invention is to provide a vise and anvil combination for a tack button wherein the vise has a double wall.

BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a top plan view of the combination vise and anvil;

FIG. 2 is a bottom plan view of the combination vise and anvil shown in FIG. 1;

FIG. 3 is a section taken through a tack button attached to a support by a tack;

FIG. 4 is a sectional exploded view of a tack button; and

FIG. 5 is a plan view of the body element.

DESCRIPTION OF THE PREFERRED EMBODIMENT There are several operations necessary to fonn the combination anvil and vise. The first step is to take a cup-shaped piece of metal and form a flange at its open end and then start a draw in its closed end. The length of the draw is increased in the next step. The drawn cup now has its internal wall canted inwardly to provide the form of a truncated cup and the diameter of the flange is increased while the diameter of the aperture is slightly decreased. At this point the former closed end of the cup lies on the same plane as the flange portion.

The tack button comprises a cap element 10, a body element 12 and a combination vise and anvil l4.

' The cap element 10 includes a circular base having its peripheral edge turned up to provide an annular skirt portion 16.

The body element 12 includes a centrally located, domeshaped portion 18 which merges into a horizontally extending step portion having its edge flared upwardly and outwardly to provide a rim 19.

The one-piece combination vise and anvil 14 comprises a truncated cone-shaped hub defined by an external, continuous, uninterrupted wall 20 having a flange 22 extending annularly therefrom. An aperture at the top of the truncated hub leads into a cuplike portion which is defined by an inner wall 24 and closed at its lower end by an anvil portion 26. The external wall 20 1S slightly spaced from the inner wall 24 and rs the flange 22 of the combination vise and anvil against the base of the cap element 10. In this position, the skirt portion 16 circumscribes, in spaced relation, the combination vise and anvil 14. The body element 12 is placed within the cap element 10 with its rim l9 circumscribed by the skirt portion 16. The skirt portion 16 can now be upset against theexternal surface of the rim l9 securedly attaching the three elements together. The hub of the vise and anvil 14 protrudes up into the dome-shaped portion 18 of the body element 12.

To attach a tack 28 to the button and a fabric support 30, the sharp point of the shank of the tack 28 is passed through the support 30 into a small starter hole formed in the domeshaped portion 18 of the body element 12. As it passes through and enlarges the starter hole it enters the aperture of the combination vise and anvil 14 andthen passes between the inner wall 24 and finally butts against the anvil portion 26. The anvil portion 26 will upset or curl the point of the tack 28 completing the attachment.

lclaim:

l. A tack button assembly comprising a cap, a body element and a combination vise and anvil, the cap including a base and a peripheral skirt depending from said base, the body element including a generally tubular housing and a rim projecting upwardly and radially outwardly from one end of the housing, the combination vise and anvil element including a continuous, external sleeve having a hub and a peripheral, radial flange at one end of said hub and a vise disposed within said sleeve, said hub being disposed within said body element and said flange being supported by the rim of said body element, said vise being circumscribed by said sleeve in at least partial reinforcing abutting relationship therewith and being joined to the end of said sleeve remote from said radial flange and having one end thereof closed off by said anvil which is disposed substantially coplanar with said peripheral flange, and said vise further including a tack receiving and clenching chamber, said chamber having an inverted funnel-shaped, tack-receiving portion opening at the end of said vise remote from said anvil and communicating with a funnel-shaped, tackclenching portion adjacent the said anvil, the peripheral flange on the said sleeve and the said anvil being secured against the base of said cap by the depending skirt portion of said cap which is curled over the rim of the body element to maintain the said tack button components in assembly.
